CORN HUSKING AND CLEANING MACHINE.

SPECIFICATION forming part of Letters Patent; No. 307,339, dated October28, 1884.

Application filed March :20, 1884 (No model.) i

To aZZ whom it may concern:

Beit known that LS. MILFORD SOHINDEL,Qf Hagerstown, in the county ofWashington and State of Maryland, have invented certain new and usefulImprovementsin Corn Husking and Cleaning Machines; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

My improvements relate to that class of inventions known as corn huskingand clean ing machines, and have for their object to supply an apparatuspossessing in a much simplified manner all the attributes necessary to afull and free operation, and one that produces with greatest rapidityand effectiveness the most practical results. Prominent among results isthat the husking is accomplished so thoroughly as to prevent to agreater. extent than heretofore the escape of husks and other debris tothe cleaning-rolls, thus permitting such rolls to operate moresatisfactorily in picking or removing the silk that naturally adheres tothe car than otherwise has been done. Further, the means by which thedelivery of the corn from the husking-rolls to the cleaning-rollsjsaccomplished renders the husking and cleaning continuous and perfect.

With the advantages set forth in view, my invention consists in theconstruction and (30111- bination of parts, substantially as hereinafterdescribed, and pointed out in the claims.

Referring to the annexed drawings, Figure 1 represents, with the feedand delivery boards removed, a top plan view of an apparatusembodyingthe features of my improvement. Fig. 2 is a side sectionalelevation thereof on the liney y, Fig. 1. Fig. 3 is an end elevationshowing in section on the line a: m, Fig. 1, the picking -rolls andcleaning devices therefor and the sides ofthe frame inelosing suchrolls, also showing the feed-board in elevation, with its forward endpartly broken away and in section to more clearly illustrate itsconstruction. Figs. 4 and 5 are detail views, respectively, of thepicking-rolls and husking-rolls.

while being subject to the action of the picking-rolls. Fig. Sis adetail of the sliding journal-boxes.

Reference being had to the several parts by letter, A represents .theframework of the machine, the same being of any approved construction.Mounted on such frame-work across the top, and in suitable bearings, aa, are corrugated differentially-rotated rolls B 1), their points ofsupport being in the same vertical line, and the one of largestcircumference being preferably uppermost.

To one end of the shaft of the upper corrugated roll is a drive-wheel,1, by which the machine is driven from any suitable power,

while at the opposite ends of the shafts of both are different-sizedcog-wheels 2 3, which mesh with each other, and by which themotioncommunicated to roll B is transmitted to thelower one, 6.

Carried on that end of the shaft of rollers b 7 5 corresponding to thatend of the shaft of the upper roll that carries the drivewheel is abeveled gear-wheel, 4, which meshes with a similar wheel, 5, on the endof arotating shaft located beneath, for a purpose to be describedhereinafter.

Situated beneath the husking-rolls B b, and somewhat beyond one sidethereof, is an inclined vibrating trough, O,,which receives the corn asit is torn from the stalk and delivers 8 5 it to the cleaning or pickingrolls.

It is very desirable in machines of this character, where the pickingrolls are parallel with the husking-rolls, tohave the corn delivered tosaid picking-rolls lengthwise there with, so as to permit the corn to bemore read: ily received by them and cleaned. If the ears are deliveredthereto in a jumbled mass, the working of the rolls is retarded, andbreak-.

age of some of the operative parts is theconsequence. This is a commondefect in many machines now in use, and I propose to over come the sameby forming the bottom of the inclined trough O with slats 0, so that thecorn,

when it falls therein, is induced to take a'di- 10o rection coincidentwith the length of the picking-rolls, and thus be received into theirworkingbite and thoroughly cleaned. This trough O is supported at itsupper end in a hole in the frame A (see Fig. 2) by a pin, 0, which movesin and out of said hole as the trough is vibrated. The lower end of thetrough is loosely supported from the frame or sides (Z d of the boxinginclosing the picking-rolls by straps or pendants 0 0, thus permitting afree vibrating motion. This motion is obtained by means of a cam, c,that is carried by a rotating shaft, D, located in and borne by theframe beneath. and at a point near the center of the trough. Theshaft 1) is supported in line with the bottom of the trough, and carriesat its outer end the beveled gear-wheel 5, that receives its motion fromwheel 4, and is thus rotated. The ends of the cam 0' come in contactsuccessively with lug con the bottom of the trough. It is evident,however, that other means than those just described could be employedfor the same result. The inner end of shaft D carries a cog'whecl thatis permitted to rotate in a true vertical plane by virtue of a joint, f,in said shaft. This wheel is also secured to the shaft of the outerpicking-roll, (represented byx, Figs. 1 and 4,) and constitutes one ofand meshes with anotherone of a train of cogs, g, carried by the innerends of the shafts of the picking-rolls E, and by which they areoperated to revolve in pairs in opposite directions, as indicated by thearrows, Fig. 4. One roll ofeach pair of picking-rolls is preferablyprovided with pins, or bearded, as it is commonly called, and the otheris of smooth surface in order to move effectually clean the ears. anysuitable material, and have their bearings in boxes s,that slide inslots or grooves in cross-beams (5 and 7. (See Fig. 8.)

Extending between the non-working bites of the picking-rolls above andlengthwise of the same are square strips h, of iron or other suitablematerial, which constitute cleaning devices for said rolls. They areloosely secured at their ends by pins or screws that pass throughelliptical slots at in the cross-beams 6 and 7 of the frame, or in thecleaners thenr selves, see Fig. 1,) which allow them to turn and riseslightly at either end to yield to masses of silk and husks that mightaccumulate and retard the working of the rolls. Their function is togather the surplus silk from the rolls as the corn is operated uponbetween their working-bites, and cause it to be precipitated betweensaid rolls to the ground beneath. In addition to this function, however,should the corn as it is fed to the rolls strike upon them, it is causedto glance off to one side or the other by virtue of their contour, andthus assist to prevent the non-cleansing of a single car. They arepreferably square in cross-section, and an angle formed by two of theirsides rests between the rolls, as shown in Fig. 4. Their two under sidesare preferably bearded, as shown in detail, Fig. 6. This They are madeof figure shows a slight deviation from the crossseetion shown in Fig.4.; but I consider such form clearly within the scope of my invention.

Connected to the trough G at its lower end by a rod, 2', passingtherethrougl1,are two, three, or more devices, F, that are caused tovibrate with each vibration of the trough. Their outer ends are looselysuspended by straps Z, that are secured to strips m, extend ing acrossto the sides (I (7, in order to allow said ends to rise and fall. Thesedevices serve two functions, to wit: First, being serrated or otherwiseroughened on their under surfaces,

and having imparted to them a vibrating 1notion, they act to graduallyimpel the corn forward to the delivery end of the picking-rolls, whileit is rotated by their cleaning action; second, in the event of an earof corn, while passing over the picking-rolls, being thrown upon end,hese devices at first slightly yield upward b virtue of their flexiblesupport atthe outer ends, and then by their continuous vibrations theyact to again force it down without breakage or stoppage of any part ofthe machinery. In Fig. 7 I have shown these de vices as being one solidapron, which would serve with good results in some instances; but inpractice I prefer to use them in the form just described.

G represents the feed-board for the stalk to the huskingrolls, which isformed at its end nearest such rolls with an opening, Z, extendingentirely across for the passage or drop of the corn as it is pinchedoff. An inclined board (see dotted lines, Fig. 3) is situatedjustbeneath the lower husking-roll, to guide or direct the corn, as itfalls, upon the trough C.

II represents the delivery-board for the stalk after its passage throughthe huskingrolls.

In Fig. 5 are represented in dotted lines boxes 8, for the shafts of thepicking-rolls, which slide in longitudinal grooves or slots in thecross-beams 6 and 7. At each end of the beams is a spring, 2, whichbears between the sides of the end boxes and a small disk, 8, and whosetension is regulated by a set-screw, J. The purpose of these slidingboxes is to allow the picking-rolls to break gear and yield either wayto any obstacle that otherwise would retard their operation, and aftersuch obstacle has passed through to be again forced into gear by theresiliency of the springs. I11 this figure a nest of but four rolls isshown, which would only require a spring at each end of the supports inwhich their bearings are held; but of course in a nest of six, as inFig. 1, a spring would have to be located and arranged inter mediate ofthese. I11 said Fig. 1 these sliding boxes are not illustrated, in orderthat the other connections of my apparatus may be shown.

The operation is as follows: The stalk c011- taining the ear of corn tobe husked is placed upon the feed-board butt foremost and ad- .vancedagainst the husking corrugated rolls B b. The rolls seize the stalk,rolling it through upon the delivery board H. The ears of corn, uponreaching these rolls, strike the larger one butt first, and are bent orturned downward at an angle, while the pull upon the stems is in astraight line, and is a gradual, even, and thorough tearing one. Thehusked ears drop into the vibrating trough G, where they are made toassume a direction coincident with the length of the picking-rolls byfalling into employment of the corrugated rolls operated atdiii'erential speeds I obtain with a much smaller expenditure of powergreater results in agiven time than are accomplished by many machinesnow in use.

Having thus described my invention, what I claim is 1. The combination,in a corn-husking machine, with the corrugated bushing-rolls and meansfor revolving the same, of the inclined slatted trough and the means bywhich it is vibrated, the picking-rolls, and the serrated devices F, allconstructed and arranged sub stantially in the manner described.
